摘　　要：为了验证1.5%嘧菌酯·咯菌腈颗粒剂对辣椒根腐病的防治效果,本研究开展了辣椒根腐病田间防治试验,其中选用20%二氯异氰尿酸钠可溶粉剂、1%嘧菌酯颗粒剂和2%咯菌腈颗粒剂作对照药剂。结果表明,1.5%嘧菌酯·咯菌腈颗粒剂有效成分用量为337.5~450.0 g/hm^2时防效达81.82%~87.88%,1%嘧菌酯颗粒剂有效成分用量为450 g/hm^2时防效达84.85%,2%咯菌腈颗粒剂有效成分用量为150 g/hm^2时防效达84.85%,20%二氯异氰尿酸钠可溶粉剂防效达81.82%,各药剂防效相当。生产上推荐采用1.5%嘧菌酯·咯菌腈颗粒剂有效成分用量337.5~450.0 g/hm^2进行辣椒根腐病防治。The purpose of this study is to verify field control efficacy of azoxystrobin·fludioxonil 1.5%granule against pepper root rot disease,with sodium dichloroisocyanurate 20%soluble powder,azoxystrobin 1%granule and fludioxonil 2%granule as control.The results showed that the control effect of azoxystrobin·fludioxonil 1.5%granule 337.5-450.0 g/hm2(amount of active ingredients)was 81.82%-87.88%,the control effect of azoxystrobin 1%granule 450 g/hm2(amount of active ingredients)was 84.85%,the control effect of fludioxonil 2%granule 150 g/hm2(amount of active ingredients)was 84.85%,and the control effect of sodium dichloroisocyanurate 20%soluble powder was 81.82%.The control effect of each pesticide tested was comparable.It is recommended to use azoxystrobin·fludioxonil 1.5%granule 337.5-450.0 g/hm2(amount of active ingredients)for the prevention and treatment of pepper root rot disease.
